For some time now, MSN Messenger has been used to spread viruses. During a conversation, a user receives, apparently from his contact, a link inviting him to open a file that looks like a photo. The file is in fact executable code that contains a virus. Once the user opens the file, the virus runs itself and is spread to everyone on the users contact list.

The Clean MSN Virus tool detects and deletes the various viruses that are spread via MSN Messenger, which are generically called MSN or MSN Messenger viruses.
